{"version":"1.0","type":"rich","title":"Test StreamGraph","description":"This visualization shows the popularity of eight baby names (Amanda, Ashley, Betty, and others) over time using a streamgraph with stacked, layered areas. The React component wraps D3 v5 APIs including `stack`, `area`, `curveBasis`, `stackOffsetSilhouette`, and `stackOrderInsideOut`. It uses `scaleOrdinal` with the `schemeDark2` color palette and `scaleLinear` for axes. Hovering over a stream highlights that category and displays its name in a tooltip, while non-hovered streams fade to 20% opacity. The data comes from the provided CSV dataset containing yearly name counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5d575dc105ce48b9811a6f500df1b25d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
